Keep long-lived projects aligned on product purpose while deep technical work moves through narrow local failure modes. Use when standing up a new multi-session project or when restructuring an existing project whose docs mix durable intent with volatile execution state.

Run long-lived, drift-prone work as a serial, disk-backed program with one narrow pass per fresh thread, explicit authority order, a task-specific checklist, and on-disk handoffs.

Use when creating, revising, or critiquing charts, dashboards, analytical figures, tables with visual encodings, KPI displays, maps, or evidence-heavy reports. Optimizes for truthful comparison, high information density, direct labeling, documented data, restrained visual design, accessibility, and rendered-output verification. Do not use for general frontend layout, marketing pages, decorative graphics, or non-data visuals unless evidence display is central.
